I am thinking about getting 22" 9.5 rims for a 1500 chevy crew cab and i was wondering if 9.5 is to wide? i lowered the back end with 2" shackles... what do you guys think?

 

Thats what i have under my o3 2wd. my rear end is dropped about 2 inches as well, and theres no issues, lots of room in the rear. The front however you must be careful, mostly with tires, as you can end up rubbing in the fenders on big bumps or at max steering position on the A arms as i do. Stick with a smaller tires than a 305/45, and you should be ok. Remember to make sure you don't get a high pos. offset. 14mm seems to be what i remember on mine.

IMO the wider the better, it just looks cool having those fatties under there, also i can hook quite a bit better.
